WONW has been on the air in Defiance since 1948 under the ownership of Tri-State Broadcasting, Inc, and started as a
full service radio station with news, sports, music, and other events. WONW was a long time affiliate of the
Mutual Broadcasting System until MBS shut down in 1999. It was in 1989 when WONW changed ownership for the first time when they were acquired by Maumee Valley Broadcasting, which at the time, owned now-sister station WNDH. Maumee Valley Broadcasting would later acquire now-sister FM station WZOM in 1994. WONW would be sold for the third time in 2000 to now-current owner
Clear Channel Communications (now iHeartMedia). In 2000, WONW's format changed from
country to
adult standards. It would remain the format until 2006, when WONW would become a news/sports/talk station, a format they used briefly in 1998 before returning to country. ==Programming==
